Efficient thermal protection is of great significance for electronic devices. Herein, we demonstrate a novel thermoswitchable microsupercapacitor (TS-MSC) with the self-protection function utilizing the thermodynamic behavior of a smart electrolyte, a lithium salt–dissolved polymer sol, poly(N-isopropylacrylamide)-g-methylcellulose. Benefiting from the reversibility of ionic conductivity, the TS-MSC exhibited a broad temperature window (30–80 °C) and totally switch-off behavior at 80 °C, as well as excellent cycling stability upon heating/cooling cycles. In addition, the thermal protection of on-chip integrated MSCs in series or parallel was achieved by controlling a single TS-MSC connected with a computer CPU under different working conditions. Therefore, TS-MSCs are promising components in the thermal protection of practical on-chip electronic devices.

可热切换的片上微型超级电容器：一种潜在的电子设备自保护解决方案†

高效的热保护对电子设备具有重要意义。在本文中，我们演示了一种新型的具有自我保护功能的热切换微超级电容器（TS-MSC），它利用了智能电解质，锂盐溶解的聚合物溶胶，聚N-异丙基丙烯酰胺-g的热力学行为-甲基纤维素。得益于离子电导率的可逆性，TS-MSC具有宽广的温度范围（30–80°C）和在80°C时完全关闭的特性，以及在加热/冷却循环中的出色循环稳定性。另外，通过在不同的工作条件下控制与计算机CPU连接的单个TS-MSC，可以实现对串联或并联的片上集成MSC的热保护。因此，TS-MSC在实际的片上电子设备的热保护中是很有前途的组件。
